Speed Limit Changes. Effects on Speed and Accidents

摘要

In the autumn of 2001, speed limits were lowered from 90 km/h to 80 km/h and from 80 km/h to 70 km/h on hazardous road sections in Norway. These road sections had been identified as having a high number of fatal or serious injury accidents per kilometre of road. This report presents an evaluation of the effects of these changes in speed limits on speed and accidents.
